Hello,
I have a little test application that can plug-in in our main application.
if the main application is open, it uses this object else it starts the main application.
Now I made a service that checks certain "packets" (as we call them) and calls my test application if a certain packet was received.
Instead however, of using the existing open main application, the test application starts a new instance of it. I guess it has to do something with the process being in a different session or space or something (because of being started from a service)?
(so the service calls the test application which in it's turn tries to plug-in into the main application)
Is there a way to "connect" to the existing application? I was searching into the Thread and Process classes, but couldn't find anything useful.
Can anybody help me?
Many thanks.
V.
I found a living worth working for, but haven't found work worth living for.

GetProcessById() returns a Process component, given the identifier of a process on the local computer (as parameter).

Thanks for the help.
I can get the process, but how do I use this object to attach to my current application? (or vice versa?)
|

"Process" refers to only one process! How could you refer two different processes with only one reference at a time ?!?

the problem lies in the fact that when called in a service, the test application can't see the application running. Sure I can get the Process object of the main app. What I actually need is to tell my test application that it needs to run in the same context or space (or whatever it might be called.)
Somehow there is a 'difference' when the test app is run normally or called via the service.
Sorry if I wasn't clear before, it's a complex problem.

What do you exactly mean by "the test application can't see the application running"?

To 'plug-in' to our main application, we use a dll that will call CreateObject after which we can use some functions to manipulate our main app. CreateObject will start a new application if it wasn't already running but will use the running application if it was (already running).
This works and has been tested in many of our applications.
Know we have to manipulate our application when a "packet" is arrived. (it's a message with some data attached). I'm able to discover this packet, analyze it and call a Process.Start("MyTestApp.exe", "myargument"); (this is done by the service)
For some reason, the testapp manipulates the main app correctly when called as exe, but calls up a new instance when run from the service...
hence the testapp doesn't "see" the main app running.
(PS: yep I've tried a GetObject too, but somehow that crashes.)
we're getting there  . (it's always difficult to explain these things, thanks for the patience)

If your app is a Windows Forms app, which actually supports only the single-thread apartment (STA) model, you must ensure that the thread handling the events, and the thread that created the Windows Forms control you want to update (or to be aware of something out there) coincide. This is not necessarily true by default and can lead to anomalies or even exceptions.
Another point would be for you to check if the arguments are passed correctly (maybe you need there a full path for some filenames passed as arguments).
Maybe this helped you a little bit.

I was looking into something like this but couldn't find it.
main app is VC6.0, the service and the testapp .Net 2.0.
Reading this my guess is I should look into the apartment state or something? Well at least it's a start (I had no clue at where to start looking)

these are definitely correct  .

How to display an array list of objects in a combo box?
|
|
|
|
|
Set the list to be the datasource, and set the dataitem and displayitem ( from memory ) properties so it knows what field to display.

hi all,
i have 2 action which are using the same method-methodA,sometime the methodA will access by both of the action at the same time.But,it will promp out a message said, "This method cannot be access,because it is using by other action".My question is how can i make the method run the acction in order?
any hits are welcome,
thanks in advance,
cocoonwls
note: i have create my own user control which control by timer,so sometime,they will access a same method at the same time

If you use a timer control instead of a thread timer, the actions will run in the main thread instead.
If you need threading, use the lock keyword for code that you have to make thread safe.

Hi Guffa,
I am trying use Thread Timers,but what should i declare for, Syste.Threading.Timer or System.Timers.Timer?
thanks,
cocoonwls

That depends on what you need. System.Threading.Timer is more light-weight, see if that fits your needs.

hi all,
I don't know if i can express my problem right but i hope you can understand what i am looking for.
let's start...
for an application i am developing (windows application), there is a kind of mail servicing. This mail servicing should send mails to the clients on a certain condition that i test using data from the database.
I had a problem with the client in defining the template that the mail should be sent uppon. I asked the client to define a default template to be used in all the mails and by having it i can enter it in the code. The client asked if i can leave it undefined. Meaning he wants to be able to change the template whenever he wish. He needs a special page for that.
I was thinking of something like the word templates, but till now i have no idea what should i do. I had never worked with microsoft office tools in C# coding. I think it is not so hard...
anybody can give me a clue.
by the way i tried searching the code project for a start but i couldn't find any article that helps. (maybe i didn't search correctly)
i didn't try googling yet cause, concerning code, i believe that what i can't find in codeproject i can't find anywhere.
Thanks for any help given.

You want them to be able to write a template for email text ? Just define special keys for the values you want to insert, such as <MAILTO>, and then you can use regex to replace them with the values you have for each email.

That's right..

That is what i was thinking of doing. but i don't know how to insert a template creating tool inside my application or coding one or something like that. and i don't know how to define those special keys.
Christian your always the savor in those situations thanks

Well, your template will just be a string. Your keys will be things that a user won't ever type otherwise, so I presented it looking like a node: <mailto>, but it could be $MAILTO, or even MAILTO if you like. The point is to come up with something consistent, and the user will just type a template into a textbox, such as
$POSTALADDRESS
Dear $MAILTO,
Thank you for downloading a demo version of $THEPROGRAM. As you're aware, this demo will expire on $EXPIREDATE. We hope you've enjoyed the demo, if you have any questions, don't hestitate to ask us, your designated contact at $COMPANYNAME is $CONTACTEMAIL.
Regards,
$MAILFROM
And so, you just load that into a string, and for each email, make a copy, then call the replace method on the string class to replace each of the keys with the value for that email.

Well, you're rendering it, so you can render it over a bitmap if you want to. I expect you can also insert a bitmap into an email, although I'm not exactly sure.
